Abstract
The invention discloses a method for preparing nano-barium sulfate coproducing sodium chloride. The method is technically characterized in that barium chloride and sodium sulfate undergo reaction according to a certain proportion and then filtration so as to obtain precipitated barium sulfate and sodium chloride. A filter cake obtained from the filtration is washed, dried, crushed and then packaged into a nano-barium sulfate product. The filtrate obtained from the filtration undergoes reduced pressure distillation so as to obtain an industrial salt sodium chloride product. The method is simple, fast and clear and particularly suitable for the production of high-grade precipitated barium sulfate by utilizing low-grade barium chloride and sodium sulfate. The method has simple production process and apparatus and achieves extremely high yield and great profit.
Description
Technical field:
The present invention relates to a kind of technical field of filler preparation, especially a kind of method for preparing nano-barium sulfate coproducing sodium chloride.
Technical background:
The method of producing process white is a lot, mainly based on barium ore production.But the production productive rate of this method is lower, and the material volume of traffic much causes production unit complicated and huge.Method with the process white of bariumchloride and sodium sulfate preparation is simple and direct and lucid and lively, particularly produces the process white of top grade with rudimentary bariumchloride and sodium sulfate, and the simple productive rate of production technique and equipment is very big, and profit is very high.
Summary of the invention:
The invention provides a kind of method for preparing co-production sodium chloride of precipitated barium sulfate, this method is simple and direct and lucid and lively, particularly produces high-grade process white with rudimentary bariumchloride and sodium sulfate, and the simple productive rate of production technique and equipment is very big, and profit is very high.
For reaching above-mentioned purpose, technical scheme of the present invention is:
The water-soluble 4-8% of using of bariumchloride (5) tensio-active agent is handled the back evenly to be stirred injecting reactor (1) lining respectively with 300-500 rev/min rotating speed simultaneously with the mass ratio 1 of dissolving sodium sulfate (6) well with pure substance: 0.38-0.98, carry out the mixing liquid that obtains barium sulfate and sodium-chlor of chemical reaction, centrifugal (2) filter filter cake sodium nano-barium sulfate again through the washing, dry (3), pulverize (4), be packaged to be product, filtrate obtains Industrial Salt sodium-chlor through underpressure distillation.Its chemical equation is:
BaCl
2+NaSO
4＝BaSO
4+2NaCl
Description of drawings:
This figure is a process flow sheet of the present invention, wherein:
1---reactor, 2---whizzer, 3---drying machine, 4---pulverizer, 5---bariumchloride is given stockline, and 6---sodium sulfate is given stockline.
Concrete embodiment:
Embodiment one: the tensio-active agent of 500 kilograms of (5) water-soluble usefulness 1% of bariumchloride is handled the good sodium sulfate (6) of back and dissolving evenly stir with 300 rev/mins rotating speed simultaneously injecting reactor (1) lining respectively with the mass ratio of pure substance 1: 0.38, carry out the mixing liquid that obtains barium sulfate and sodium-chlor of chemical reaction, centrifugal (2) filter the filter cake process white again through the washing, dry (3), pulverize (4), be packaged to be 311.76 sodium nano-barium sulfate products, filtrate obtains Industrial Salt sodium-chlor through underpressure distillation.Its chemical equation is:
Embodiment two: water-soluble usefulness 3% tensio-active agents of bariumchloride 500 kilograms (5) are handled the good sodium sulfate (6) of back and dissolving with the mass ratio of pure substance 1: 0.98 injecting reactor (1) lining evenly stirring with 500 rev/mins of rotating speeds simultaneously respectively, carry out the mixing liquid that obtains barium sulfate and sodium-chlor of chemical reaction, centrifugal (2) filter the filter cake process white again through the washing, dry (3), pulverize (4), be packaged to be 560.1 kilograms of sodium nano-barium sulfate products, filtrate obtains Industrial Salt sodium-chlor through underpressure distillation.
